New here....anyone have weird arm/leg sensations

I have been struggling with a dizziness problem for 3 years. Been to all the Drs, brain scans, heart tests, blood tests, you name it. I have been freaked out thinking I have MS and they just can;t find it yet.
It all started with a dizziness, but has now come turned into weird sensations in the arms and legs. Does anyone ever feel like thier arm or leg is not there?
Not sure if this makes sense, but it happens for a split second, then goes away. I also have feelings of weakness, but only for a few seconds. Neuro did tests for weakness, but I don't have any that he can see. I also have very figety legs and I get internal shakiness at night when trying to sleep.
I have this on and off all day long, then it goes away for a few days, then comes back. Going on 1 - 1.5 years now.
Do I have anxiety from not knowing why I get the dizziness, thinkign it's MS and my brain is mimicking MS symptoms? Drs don't see anything wrong, however I have heard MS can take years to show.
Anyone have these weird arm and leg symptoms?
Sorry for the long post...
Thx for anyone's thoughts,....Rachel

Hi I have weird sensations of tingling in one or both arms/legs. I get dizzy too, I have had an Mri, but its been 2.5 years, Id like another, and one of the spine. Have you had an Mri of your spine?
I think I have MS as well. I hope we dont.

I havealso been awakened by body shaking like someone was shaking the bed, weird.

I have had this also, arms, legs and the butt that is so weird also, I have had the thing that it feels like the bed is shaking I wake up hubby and ask him if he feels that and he says no, so I wondering what it is???

Yeah, I hope we don't have it. I have had a spine one. Cervical only. It was normal.
Do you get any other symptoms? What is your dizziness like? I don't have vertigo, I have a imbalance rocking feeling... sort of like a lightheadedness also...
It's the worst. I just want to feel NORMAL again. I think about it 24/7.
May I ask how old you are? I am 35 now.
